3 Claims.

1 This invention relates to heated-forms torprmgressively casting tilewalls inplace; and a methd of placing reinforced clay and curing, it

place.

The usual method of construction: of tile-structures is by use ofprecast blocks laid in thesame manner and secured the same as brickiii-mortar- An object of this invention is to eliminate. this old methodand shape the Wall with wi-re meshreinforcing and then curethewall inits-.perma nent position.

This method, therefore, will construct homes. that are inexpensive,durable, termite-proof and fire proof. and less cost with tlus :methodthan-with the methods previously used.

With these and other objects andadvantages in view the inventionconsists of the novel details of construction, arrangement, andcombine..-

Figure 13 is a sectional View on the line l3-l3 of Figure 12.

Referring more in detail to the drawings, the reference numeraldesignates a wall form which is slidably mounted for vertical movementwithin the frame 22.

The form Zil comprises outer side walls 24, removable end walls andclosed top 28. Secured to the top 28 by welding or other means are theinner walls Ell which are parallel to the Homes can be built withgreater speed 2- I outer walls 24, and spacedtherefrom transverselythedesired thicknesgmfthe: wall A,. which-is constructed ofclay: orsi-milar materials. The

walls 2% are made.- removable sothat the claycan be placed against theformed wall section.

or clay can be placed against clay during? the forming ofsubsequentwalls sections;

The inner walls Sit-extend longitudinally of the form 213 and are joinedat theirendslby inner end: wallet-2 to formvertical-tubes orcompartments 34.-

The outer sidewalls 24 and the interionof the. tubes-3.4 are coveredwith asbestospr similar. material: 36 that have the heating elementsembedded therein and. current.issupplied-thereto by the powerline 40.,

The hea-tin'g elements 38. onthe side Walls 24 are positionedintermediate L-beams 42 .which are placed at the upper and lower edgesotithe form and extend longitudinally thereof .to function .as guidesforthe-form within: theiframe :22; and the ends thereof are joinedbymeansofL-beams. 43.

Extending longitudinally ofthetop .23 andsecured-thereto by weldingg-atthe: medial. line. thereofiszthe channel iron beam. 1 Thisbeam. 44 withthe beams 42 serve to strengthen. and reinforce; the .fonm- .20.-.

A-pipe 45 secured-tothe-form at. the medial point thereof serves-to--feed:.the clay intmthe. form it is pumped -.thereto-by. means ofthe pump jack 48.

The-frame- 22 comprises vertical- L-beamsill which receive the ...beams42. and function as guides .for. the. form :20. as. it uses vertically.The beams 56- are disposed on opposite side'sof the forms at the outerends thereof and are formed at their upper edges *byhori'zontal longitudinally'extending'L- beams 52' and'transverse extending L-beams 54 makinga compact unit which is further strengthened by means of the crossedsteel strap braces 56.

The ends of the form are provided with half tubes 58 which will coactwith other half tubes when the neXt section of wall is joined to castthe vertical air spaces in the walls caused by the tubes 34 and halftube 58.

The inner sides of the end walls 26 are provided with verticalrelatively spaced steel rods 60 welded thereto which form verticalgrooves in the walls as they are constructed. These grooves are adaptedto receive ties to secure alignment of the segments formed by thismethod in constructing the walls.

Secured to the lower L-beams 42 at an inthrough the longitudinallyextending slots 66 formed in the top 28 of the form.

Hooks 68 secure the ends of the wire mesh in position with relation tothe form 20 and I- beams 50. At the time the wire mesh 64 is rolled thetin liner is rolled with it so that as the wire mesh 64 is embedded inthe wall the liner 76 passes between the inner surface of 'theouterwalls 24 and the wall under construction as shown in Figure '7.

When the wall segment is being formed, the

precast tiles 12 are laid at the bottom thereof to form openings topermit blowers for controlling the heat applied to the segment to beinserted therein as shown in Figure 9.

In Figure 1, a block and tackle I4 is shown connected to the frame tolift the form manually when it is desired to move it from location tolocation.

In Figure 2, the L-beams 52 are notched at 16, where the I-beams areconnected thereto to prevent end play and retain the beams in truealignment with each other.

In Figure 7 the connections to the pipe 46 are shown and a flexible pipe18 is connected to the series of elbows 80 on the pump jack 48 whichcomprises the housing 82 and screw 84 to which power is supplied throughthe shaft 86 for forcing the clay into the form 20.

In Figures 11, 12 and 13 the form 90 is L-shaped to construct the cornersegment otherwise, the construction remains as previously described,except that the corner tube 92 is formed at the corner of the segment asshown in Figure 13.

The channel iron beam 94' is now L-shaped in form and the pipe 96 isconnected thereto as was the pipe 46 to the channel iron 44.

The I-beams 98 lie at right angles to each other and the longitudinallyextending L-beams I00 connect their upper ends and their ends areconnected by the transverse beams I02.

This invention consists of a heated form for shaping soft clay andpartially curing it sufiiciently to hold its shape and place until thewall is completed and this is accomplished by the following method ofoperation:

The clay which has been previously mixed is pumped to the form 2!] bymeans of the jack pump 48 and as the form fills it will rise slowly bythe power of the incoming clay forced therein by the pump 48. After thewalls have been poured to the desired height, the voids therein formedby the tubes in the form are filled with coal, charcoal or coke which isignited, the wall is draped with an asbestos tarpaulin, blowers areapplied as previously described and the cooking continued. When the wallcontains the correct amount of heat salt is applied to make the glazeand is cooled under the tarpaulin to minimize cracking.

As the clay is supplied to the form the heating units connected theretowill start to heat and cook the clay so that as the form rises the clayhas started to harden and will be partially cooked when the desiredheight has been reached.

Forms can be made to cover openings under and about windows and doors,and the foundation is excavated and leveled before the forms are placedin position.

It is believed that the operation and construction ofthe form and themethod for making the wall will be clearly understood by those skilledin the art and that modifications and changes in the arrangement andcombination of the various parts used to carry out the invention may beresorted to without extending beyond the spirit and scope of theinvention.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

l. A structure for constructing a wall comprising a form having outerside and end walls and a closed top, vertical tubes in said form, meansfor feeding material to said form, a frame for slidably mounting saidform in said frame for vertical movement, and heating elements securedto said outer walls and the interior of said tubes.

2. The invention as in claim 1 wherein L- shaped beams are secured tothe upper and lower edges of the form to function as a guide for saidform, and upwardly inclined rods are secured to said lower L-shapedbeams for supporting a tin liner and wire mesh.

3. The invention as in claim 1 wherein longitudinal slots are providedin the top of said form to permit a tin liner and wire mesh to be fedinto said form.
